I shared this with the teachers but it just occurred to me that many of my students (and their parents) might benefit from this just as much as the teachers. One thing my husband always continually taught me about computers was to back up everything, in multiple places. This is a great free online book that walks you through the how’s and why’s of backing up data. It’s written in plain English and the author did a great job laying things out clearly. I hope you look at it and follow the advice of backing up your stuff!
